^MWANZA STD TREATMENT TRIAL--BASELINE COMMUNITY DATA^

A cluster randomised trial was carried out in Mwanza Region, Tanzania to
measure the impact of improved STD treatment services on HIV incidence in 
the general population. Twelve communities were matched into six pairs and 
one community in each pair was randomly selected to receive the intervention. 
This file, with one line of data per community, contains baseline data on the 
communities. It can be used to illustrate automated matching algorithms.
